Like reference characters denote correspond ing parts throughout the several views. The present invention comprises but relat-ively few moving parts which include a-ropackage ar er" disposed between the V casing periphery and a central stationary drum, this drum being provided with a par,-

tition, vertically disposed and located off center, that is; to one sideofthe center ofthe drum 'andtoth'e opposite lateral faces of said partition the actuating'mechanism"is secured.

7 Should repairs or replacements be necessary this partition and its appurtenances can be readily removedlfrom'the drumv and worked iupo'n "without disturbing the rest of the mechanical assembly. The machine may be provided in thecounter type, adapted to stand upon a table, counter or like support, or

may the wall type, adapted to be suspended from'a hook secured in awall. I

The'reference numeral 1 denotes the casing having thebac'k 2 and provided with the sevl er albolts' 3 adapted to be-receivedinto the I F 2 il-' .lu'stratingthe bayonetslot in the cover plate cover or face-plate 6 whereby to releasably secure saidcasing and cover together.

A lock .7, key operated, is carried by the be transmittedto theshaffl Fast upon said shaft 9"co1itiguous to'the' bearlng S'isf'the casing whereby the cover '6 may be securely fastenedtthereto.

bayonet slots 4 formed in the flange 5 of the 7 spider 13 to the outer ends of which the annular carrier 14 is secured that is formed with the flange 15disposed at a right angle thereto, said carrier and flange carrying the V- shaped partitions 19, spaced apart to separate the packages of goods to be dispensed, one package or parcel being placed between any two successive partitions. The goods arranged in the carriage 14, 15 are visible to the public through the windows 16 arranged in a circle, spaced apart, in the cover plate.

Fast to the spider 13 and centered upon the shaft 9 is a locating and locking disc 17 formed peripherally with the elongated teeth 18, the free ends thereof being pointed, the

successive teeth being spaced equal distances .25 for the shank 26 of the gate 27 that nor mally'closes the said package delivery perforation 23 said gate being formed with the spaced para lel guide ribs 28 adapted to ride in the said perforations 24 and the shank being formed with a longitudinally disposed .central guide rib 29 that, as the shank and guidemove back and forth along the inner periphery of said drum, rides through a clearance recess 30 formed in the upper end of the vertical partition 31 that spans said drum, oifcenter, said partition being secured by bolts 31a to said drum and formed at its ends with feet 32 that are bolted or riveted to the drum. Q i

Spaced upwardly from the lower end of the partition 31 and secured by rivets 33 to one face thereof is a metal guide or cover plate 34 which is spaced outward slightly from the partition, throughout the greater part of its extent, to provide a guide for certain movable parts to be hereinafter described, one portion 35v of said guide being contiguous to the lower opening inthe conventional type of coin receiver 36 the mouth of which is in registry with the coin opening 37 in the cover plate 6. I A slug chute 38 extending diagonally through a perforation in the partition 31 is disposed beneath a slug-discharge opening in the coin receiver to receive such slugs as may be discharged therefrom, said chute 38 extending through a perforation 41 inthe metal shield 39 and terminating in the contracted discharge end 40 from which the slug is precipitated outside the machine through the opening 42 in the cover plate.

A guard plate 43 secured to the contracted end of the chute and riding against the partition 31 protects the mechanism assembled upon the. partition from being tampered with, jimmied or pried out of place by mis- Fulcrumed upon a bolt 44 to thepartition 4 31 is the lever 45 that extends out through a perforation 46 in the drum back 21 and 'througlran elongated perforation 47 in the cover plate. A eturn spring 49 connected by pin 50 to the lever 45 is connected at its upper end to the partition 31, said spring engaging the lever between its fulcrum point and its outer end. I

Between the fulcrum and inner end of the lever the same is formed with an elongated slot 51 in which a sleeve 52, provided with a washer 53, rides; a rod 54 having its lower end bent to. pass into said sleeve to Which it is made fast, said sleeve 52 extending also through a vertical slot 55in the partition and .operatively engaging a riser plate 56 that slides. over the opposite "face of said partition 31between the same and the guide 34, the upper end of said riser plate is recessed to provide one narrow extreme termination 57 and a relatively lower upper edge 58, the latter edge being. normally disposed immediately below acircularperforation 59 spacediinmediately aboyethe upper end of the said-verticahslot 55, said perforation 59 normally receiving the bevelled end of a lug or'spur 60 carried at one end of a-iiat spring 61 terminally secured by the rivet 62 to the cover guide 34 and serving as a guide spur for the'coinwhen the same is in positionupon the raiser plate 56. f V I Referring again to the rod 54, that rides upward from the sleeve 52, it has fast thereupon a stop collar 63'that receives one end of an expansion. coil spring 64 that encompasses said rod and also encompasses a metal sleeve 65 that is loose upon said rod, said sleeve being of less length than the spring in the normal position of the same, the upper end of said spring abutting a block 66 formed with a reduced portion 67 that extends through avertical slot 68in the partition 31 and is fast to a flat plunger plate 69 that rides over the face of the partition remote from block 66,. another vertical slot 70 in the partition 31 beingspaced from the slot 68 and parallel thereto and providing clearance forthe lower end or heel 71 of the slightly curved gate-control lever, 72 fulcrumed upon the pin. 73 to a partition 74 which ispunched out, all but one edge, from the metal guide 34, an angular arm 75 fast tothe forward end of said gate-control lever being connected by the lever-return spring 76 to the coin receiver 36. 7 j

The forward extremity of the. lever17 2 is formed with the bifurcation 77 topermit. its

operative engagement with the inwardly bent end 78 of the gate shank. 26. l 2

The said lever has its inner end bent laterally. with respect to the partition 31, and terminating in anuintegral block '79 which is recessed to receive one end ofa finger 80 parallel with the lever axis and terminating beyond the adjacent open end of the drum 20. A pawl 81 pivotedlto one face of the block 79, atrightangles to the finger 80,,is engaged by the springS-Qand adapted to work over the rack 83 formed upon the contiguous face of the partition 31. In the normal position of the lever 45 the pawl 81 is out of engagement with the raclr83; but as the lever is moved upongits fulcrum. by

depressing its outer end thepawl rides over the teeth of said rack.and,.-until it passes beyondthe upper end .of therack, prevents. a return movement-of the lever fromxany ad justed position. The leveris yieldingly'retained in said normal position bythe' spring 49. q

The lower edge of the plate 69 is'isomewhat irregular and comprises a finger .84 that rides over the partition 31 in a position ofiset from the top edge 57 of'the riser 56,;with a bevelled lower edge portion 85' that runs .from said finger obliquely upward and terminates in the arcuate recess 86., a small V81? ticalf slot 87 in said plate rising from the edge 85, said plate 69 being formed alsowith a stop lug 88. contiguous to the heel/1110f lever 72-for abutment with the lower .endof theslot 70 to arrest the further downward movement of the plate 69 and its connections. p

An angularwbracket 89 securedto the par- .tition 31 has the lower end of a "locking lever 91 secured thereto by pin or'rivet 90, the pin being somewhat smallertha-n the perforation in the lever so that a limited movement-,or play of the lever, vertically,ispossible, said lever being formed. adjacent its pivoted .end with a bevelled spur92 that isJ-yieldingly projected through the. said slot 87 in the plunger plate 69 andthrough. a slot .93; in

the partition 31; with which said slot. 87'

registers; said lever 91 beingformed further with the spurs .94 and 95 bothof which nor-- mally project through the elongated slot 96 in the partition 31, sa d-slot 9.6 beingofgreater length than the distance from the-lower I edge of the spur-94, to the .topedge'of spur 95 so that clearance is provided :for a certain play or degree of movement of thelever relapartition 31, one end of said link being engaged andyieldingly retained in normal position by a contractile spring 100secured by pm 101 to the partition, the end ofsaid link remote from said spring carrying a round pin 102 disposed inanarcuate slot 103 formed in. said partition, said pin. being yieldingly retained in one end of said slot in engagement with. the arcuate recess 86 in the plate 69 through the action of the spring 100. A coin box. l04is securedto the partition 31 beneath,

or encompassing, a recessed portion 105 in the guide plateB l through which the coin is ejected after having served to operate the machine in a manner to be hereinafter de--.

scribed. In. the drawings the coin box is show-n. materially smaller than it is intended to be. This is to prevent'obscuring certain portions of. the operating mechanism.

The coinbox is provided with a gate 106 and said box is formed witha out out portion 107 to provide clearance for spring 61.

The operation isas follows: Theoperator surveys the contentsof the machine through the windows 16. Any package selected must be brought to a position visible through the I .window 16 indicated by the arrow 108, Fig. 1. Thisis done by rotating the carriage 14, 15

carrying the packages or goods. He now drops a dime in the coin receiver 36 which .di-mepasses throughthechute or guide portion 35- and then through a passageway .formed by. the partition and'the guide 3ft. The d'me is visible as it passes,1or drops, past thezcorner 109 of the large cut out portion of the guide wall 34L, the passageway then causes it totraveliinmediately below the pin 102 and-to lodge between the guide and partition upon the end 57 of plate 56, resting against the finger 84 and immediately below the recess 105' in guide plate 34. The dime travels over this distance to this locat on almost instantly. To release the parcel the operator now manually depresses the outer end- 110 of the lever 45. This lever will move thefi-nger v80 upward and between two of the elongated teeth '18-which willlock the spider 13, disc 17 and carriage 14, 15 and position thepackage sought directly in alignment with the delivery opening 23 in the drum 20. a i

At the same time the lever 45 will raise the rod 54, the spring 64 pressing against the block-66 will cause the same to raise the plunger plate 69 to which the reduced 'end 67 of block 66 issecured. The dime will be raised by the riser 5.6 into proximity to the bevelle'dedge 850i plate 69 andas that plate is" raised relative to the locking lever 91 the dime will encounter the bevelled spur '92 thereof and thrust it and the lever outward upon pivotipin 90. I

The spur 9iwill :then have been thrust out of the path of the plunger plate 69 which plate can then travel to theextrerne upward end of its p ath without interference from .the

lever or detent 91. The upward movement of the plate 69 unhamperedcauses a corresponding downward movement of the bifur cated end 7 7 of the lever 72 bringing with it the gate shank 26 and gate 27 thus uncover- .ing the package delivery perforation 28 and permitting the package to pass therethrough by gravitation and to fall or strike against the shield 39 and lie at the delivery opening 42 in the cover plate within the drum from which it may be removed by the operator.

While the inner end of the lever 45 rides upward the pawl 81 will pass over the rack 83 and beyond same. \Vhile it is engaging the rack it will preventa return movement of the lever should the operator not use force enough to cause it to travel outofrack; engagement. From any locked position of the pawl and rack the lever can be further moved until the full sweep of the lever is'made and the rack and pawl separated. 7

When the pawl passes out ofrengagement with the rack the lever and allconnections are free to return to normal position and this action will be accomplished through the operation of the springs 49, 64 and T6. After each return of the lever the moving parts are ready for another operation. When the dime rises into theope'ning 105 in the guard plate it also forces the pin 102 out of its path by this movement. Should a person intentionally or inadvertently drop two dimes in the machine at the same'time, both may pass through the dime passageway. One dime will stop in operative position'upon the edge 57 ofthe riser, as previously described, and the other dime will abut the first one in a position supported by the spur 60;

As the lever 45 is operated the first dime will force the second one to one side, the first dime releasing a package and then dropping into the coin box. The second dime will drop immediately thereafter into operative position ready for a second operation of the discharge mechanism so that, if the operator positions another package before the discharge opening 23 he will not lose his second dime but will receive a second package for it.

In the event that no dime is placed in the coin receiver the spur 92 of the lever 91 will not be thrust outward and consequently the plunger plate 69 will not move upward 'far enough to cause it to actuate the lever 72 sufficiently to move thegate 27 from over the discharge opening 23. hen the upward movement of the plunger plate 69 is blocked by the spur 94 the upward movement of the block 66 is likewise limited but the rod 54 rides up the full extent of its stroke, pass ng freely through the block, the block merely compressing the spring 64 to compensate for the relative movement of said rod 54. Idle manipulation, then, of the lever by a person, without dropping a dime into the coin receiver will but compress the spring 64,move

a station'ar theiplunger plate 69 and lever 72 but a portion of their full sweep, or inoperatively, and

'fail to displace the gate 27 from the opening 23. When the upper end of the plunger plate serves as a guide and retaining spur to prevent detachment of the lever from he partit1on.- Adjusting nuts 111 are arranged upon the threaded'upper end of the rod 54 to adjustthe same relative to the spring 64 so that the proper compression or tension of the latter member may be provided.
